weightedQuantile: Weighted Quantile Value

In PSCBS: Analysis of Parent-Specific DNA Copy Numbers

Weighted Quantile Value

Description

Computes a weighted quantile of a numeric vector.

Usage

## Default S3 method:
weightedQuantile(x, w, probs=c(0, 0.25, 0.5, 0.75, 1), na.rm=TRUE,
  method=c("wtd.quantile"), ...)

Arguments

x	a numeric vector containing the values whose weighted quantile is to be computed.
w	a numeric vector of weights the same length as x giving the weights to use for each element of x. Negative weights are treated as zero weights. Default value is equal weight to all values.
probs	a numeric vector of quantiles in [0,1] to be retrieved.
na.rm	a logical value indicating whether NA values in x should be stripped before the computation proceeds, or not.
method	If "wtd.quantile", then an internal copy of Hmisc::wtd.quantile() is used. No other methods are currently supported.
...	Additional arguments passed to the estimator.

Value

Returns the weighted quantile.
